Dust filter pads or air filter pads are specialized products used for industrial dust filtration and are also very effective for clean water filtration. What types of dust filter pads are there, and how are G1 dust filter pads, G2 dust filter pads, G3 dust filter pads, G4 dust filter pads classified?
1. What are dust filter pads or air filter pads?
Dust filter pads, air filter pads in general, are specialized products used for industrial dust filtration and are also very effective for clean water filtration.
There are many different types of dust filter pads used in dust filters today.
They are classified by size: 2m x 20m x thickness: 5mm (G1 dust filter pad), 10mm (G2 dust filter pad), 15mm (G3 dust filter pad), 20mm (G4 dust filter pad). With corresponding filtration efficiencies: 70%, 80%, 85%, and 90% according to European standard EN-799.
2. Uses of air filter pads:
Dust filters have many different uses and installation locations depending on the installation needs of factories. And there are various types of dust, which can be used to filter dust in many different industries such as paint dust, wood dust, or fiber dust,…
Filtering large dust particles, coarse dust, or for primary dust filtration:
- Used for dust filters in ventilation systems of buildings, factories, and workshops;
- Cleanroom filtration for pharmaceutical, food, electronics, and other industries;
- Ceiling, floor, and wall filtration for paint booths, dry paint rooms;
- Used as dust filter panels for refrigeration and industrial dust filtration;
- Filtering wood dust and paint dust in the wood and handicraft industry;
- Filtering water for seedling cultivation and aquaculture,…
- Used to filter air in hospitals, medical stations,… places where diseases easily spread through the air.
- In chemical laboratories, dust filter panels are used to filter chemical residues.
- Air compressors also use G1, G2, G3 air filter pads to produce cleaner air. Mainly used in industries requiring clean air such as medicine and food processing.
Advantages of using dust filter pads: High air flow with low pressure drop. High fire resistance and high dust holding capacity, long product lifespan
Regarding dust filtration efficiency, this is a specialized product designed for dust filtration and has 4 different levels of cleanliness. And they are named G1 dust filter pad, G2 dust filter pad, G3 air filter pad, and G4 dust filter pad.
